Statuses are indicators for the hosts or the services. Each status has a precise meaning for the object.
To each status corresponds a code generated by the monitoring plugin according to thresholds defined by the user.

An incident (Not-OK status) is confirmed as of the moment when the number of validation attempts has reached its end.
The configuration of an object (host or service) requires a regular check interval, a number of attempts to confirm a Not-OK status and an irregular check interval.
As soon as the first incident is detected, the state is “SOFT” until its confirmation into “HARD”, triggering the notification process.

Example:

A service has the following check settings:

Max check attempts: 3

Normal check interval: 5 minutes

Retry check interval: 1 minute

Let us imagine the following scenario:

Instant t + 0: The service is checked, it has the OK status.

Instant t + 5: The second check shows that the service has the CRITICAL status. The service goes into the SOFT state (attempt 1/3).

Instant t + 6: The third check is performed, the service still has the CRITICAL status in SOFT (attempt 2/3).

Instant t + 7: The fourth check shows that the service still has the CRITICAL status (attempt 3/3). The number of tests has been completed; the state is configured (HARD). The notification process is triggered.

Instant t + 8: The service recovers OK status. It goes directly into the HARD state. The notification process is triggered.

Instant t + 13: The service has the WARNING status. It goes into the SOFT state (attempt 1/3).

Instant t + 14: The service still has the WARNING status (attempt 2/3).

Instant t + 15: The service has the CRITICAL status. It remains in the SOFT state because it has changed status.

By default, during viewing of statuses of hosts or services, the monitoring data is refreshed automatically (15 seconds by default).
Nevertheless, several icons can be used to check the refreshing of the data.
The table below summarizes the functions of these icons:
